[jira] [Created] (FLINK-25769) Add internal functions and basic function versioning

Timo Walther created FLINK-25769:
------------------------------------

             Summary: Add internal functions and basic function versioning
                 Key: FLINK-25769
                 URL: https://issues.apache.org/jira/browse/FLINK-25769
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API, Table SQL / Planner
            Reporter: Timo Walther
            Assignee: Timo Walther


As mentioned in FLIP-190:

We keep the old function definition around under an internal name. The physical plan after restore might look similar to:

{code}
== Optimized Physical Plan ==
Calc(select=[$TO_TIMESTAMP_LTZ$1(f0)])
{code}

{{$TO_TIMESTAMP_LTZ$1}} has been returned by the ModuleManager.
